REVERSIBLE COMPRESSION STOP AND WASTE.

Specification of Letters Patent.

Patented ow. 20, 1908.

Application filed. August 13, I907. Serial No. 388,343.

To all whom it may concern:

Be it known that I, WILLIAM G. ROWELL, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inReversible Compression Stops and Wastes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain improve ments in reversible compressionstop and waste for the use of plumbers in the equipment of buildingswith water circulating systems. Devices of this sort are utilized forthe purpose of turning the supply of water off and on, and in myimprovement I provide two diametrically opposite exit nozzles for thewaste water one of which is always closed by means of a screw or plug,so that when the workman has installed the device he plugs up the nozzlewhich points in an improper direction leaving the other nozzle to takecare of the waste water. Also, in my present improvement, I control thedischarge of the waste water by means of a loose waste collar which iscapable of both vertical and rotary movements, the result being that thecollar washes itself by keeping all foreign substances in constantmotion so that they will be readily discharged through the exit nozzle.

In the accompanying drawing Figure 1 is a sectional elevation takenlongitudinally through the stock, or, in other words, on the line 9 ofFig. 2Fig. 2 a cross section on the line it of Fig. 1, and Fig.3 adetail plan view of the waste water collar.

Similar numbers of reference denote like parts in the several figures ofthe drawing.

1 is the stock proper which is open at the ends, as seen at 2, 3, forcommunication respectively with the water su ply and service pipes. Thisstock 1 is divi ed in the usual manner at its central portion by apartition 4: which has a horizontal portion through which is formed avalve opening 5 which latter is the sole means of communication betweenthe respective ends of the stock.

Formed integral with the stock and extending upwardly therefrom is acasing 6 which is open at the top and is interiorly threaded at itsupper portion. The lower part of the casing constitutes a waterwaychamber a, and an opening 7 is formed in the floor of this waterwaywhereby communication is established between the latter and that end ofthe stock to which the service pipe is connected.

8 is a cap having a reduced threaded plug 9- which is driven within thethreaded end of the casing. A recess 10 extends from the bottom of theplug up into the body of the cap andis interiorly threaded, and anopening 11 extends from the top of the cap into said recess. Through theopening 11 extends the valve spindle 12, and 13 is a gland surroundingthe spindle and driven on the top of the cap 8 and inclosing anysuitable packing 14. This spindle has threads which engage the threadsof the recess 10, the top of the spindle being provided with any suitable handle 15 for the purposes of convenient operation. in the usualmanner. The spindle 12 extends down through the waterway at the lowerportion of the casing 6 and has secured to its lower end an ordinaryvalve 16 which is surmounted by a washer 17 that extends slightly beyondthe periphery of the valve. The valve is of such dimensions that it willfreely pass through the opening 7 but the washer has substantially thesame diameter as that of the opening and will completely fill the latterwhen drawn up into the same.

Loose around the spindle 12 and contained within the waterway in thelower portion of the casing is a waste water collar 18. This collar iscup-shaped and is perforated in the bottom, as seen at 19, so that thespindle 12 may pass therethrough, the shape of this opening beingpolygonal so that water passages are provided, as seen at 20, at theangular portions of said opening immediately outside the spindle, bymeans of which passages communication is established between the servicepipe and the water way inside of said Collar. In the sides of this watercollar are ports 21, and the collar itself is loose around the valvespindle and is perfectly free in the waterway within the lower portionof the casing so that it will be clear that said collar is capable offree vertical and rotary movements.

22, 23, are exit nozzles which extend'from diametrically opposite pointsof this casing 6 and communicate directly with the waterway in the lowerportion of said casing so that it will be clear that water passingthrough the collar 18 will be discharged directly through these nozzles,any suitable plug 24: being provided whereby one or the other of thesenozzles may be closed as the occasion may demand.

The operation of my improvement is follows z-JVhen the valve is elevatedto permit the delivery of water from the supply into the service pipe,as shown at Fig. 1, the washer 17 will be drawn up into the opening 7,thereby completely cutting off communication between the waterway in thebottom of the casing and the service pipe, so that there can be nodischarge of water through the nozzles 22, 23. hen the valve is seatedagainst the valve opening 5, as shown at Fig. 2, all communicationbetween the service and supply pipes will be closed, and there will be adirect communication between the service pipe and the waste water collar18, and the water in the service pipe will then pass through the opening7 and the openings in the bottom of the collar outside the valvespindle, and be discharged through the ports 21 in the collar into oneof the nozzles 22 or 23.

In installing my improvement either one of the nozzles may be plugged,as the occasion may demand, thus leaving the open nozzle to take care ofthe waste water.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent isz- In a device of the character described,the combination of a stock open at the ends for connection with supplyand service pipes" is controlled, a casing integral with said stock andwithin which said valve stem is operatively mounted, said casing havinga waterway chamber which is in communication with the service portion ofsaid stock independent of said valve opening and also havingdiametrically opposite exit nozzles leading direct from said chamberinto the outside air, a plug for closing one of said nozzles,'a wastecollar loose around said valve stem and loosely confined within saidwaterway chamber, said collar having inlets in its lower portion andoutlets in its side, and a washer surmounting said valve and of suchshape and dimensions as to entirely cut ofi communication between saidwaterway and service portion of the stock when the valve is opened,whereby the depression of said valve will allow the water in the servicepipe to enter the waterway chamber and waste out through one of saidnozzles.

In testimony whereof I affix my signature in presence of two witnesses.
